How the immune response to SARS-CoV-2 may damage the brain: discovery

A post-mortem MRI study offers a clue to the cascade of events

The immune response triggered by SARS-CoV-2 infection may mistakenly target cells crucial to the blood-brain barrier and increase the risk of bleeds and clots, a small study suggests.

The findings, based on autopsies of nine individuals who died suddenly from COVID-19, suggest both short- and long-term neurological complications from the disease, according to US researchers.

The National Institutes of Health-led team say the data are consistent with results from an earlier study that showed the virus did not
